With the above configuration, after the private parts of a person sitting on the toilet seat are washed with washing water, the buttocks that leaked from the washing water are dried with warm air. (For example, JP-A-59
-107142 Publication) Problems to be Solved by the Invention However, with the above configuration, hot air is applied to the buttocks that have leaked flush water, so if the temperature in the toilet room is high in the summer, the buttocks become hot and the buttocks become hot. I had the unpleasant problem of sweating.

The present invention is intended to solve these conventional problems, and aims to cool the hot buttocks with warm air from drying.

Means for Solving the Problems In order to solve the above-mentioned problems, the sanitary washing and drying device of the present invention includes a warm air drying means for drying the buttocks of a human body leaking with washing water with hot air, and a temperature control system for the inside of the toilet room. The hot air drying means is configured to detect a room temperature, and after energizing the hot air drying means for a predetermined period of time, switch the hot air drying means to a blowing mode based on the room temperature detection setting value of the room temperature detection means. be.

Effects According to the present invention, the above-described configuration allows the heated buttocks to be automatically cooled down by warm air during the summer when the room temperature of the toilet is relatively high.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 15 is a commercial power supply and connects the blower fan motor 10 in parallel via the normally open contact R _Fa of the drying relay R _F. A drying heater 11 is connected in parallel with the blower fan motor 10 via a normally closed contact R _Hb of a room temperature detection relay R _H to constitute a hot air drying means A.

A control power source 16 serves as a driving power source for the following control means.

17 is a drying operation switch, 18 is a drying stop switch, and the drying operation switch 17 is connected to the set terminal of the R-S flip-flop 19, and the drying stop switch 18 is connected to the reset terminal. The output terminal ``'' of the R-S flip-flop 19 is ``L'' when the set terminal is ``H'', and the output terminal ``'' is ``H'' when the reset terminal is ``H''.
It is set to "H" when . The "" output is input to the gate _G1 and the NPN transistor 20. B is a drying control means, which has a series circuit of a resistor 21 and a capacitor 22 connected to the control power supply 16, a terminal voltage V _T obtained by dividing the control power supply 16 by the resistor 23 and the resistor 24, and a terminal power supply V of the capacitor 22. _c is input to the comparator 25. The comparator 25 has an inverting terminal inputted with V _T and a non-inverted terminal V _c inputted thereto. The collector output of the NPN transistor 20 is connected to both ends of a capacitor 22 via a resistor 26 to form a timer circuit. The comparator 25
The output terminal 27 of is input to the gate _G1 . The output of gate G ₁ is input to gate G ₂ , and the output is NPN
Drying relay R _F is energized via transistor 28 . The collector terminal of the NPN transistor 28 is connected to the reset terminal of the R-S flip-flop 19 via a reset circuit 29.

Next, the configuration of the room temperature detection means C for detecting the room temperature of the toilet will be explained. A thermistor 29 detects room temperature, and a resistor 30, a resistor 31, and a variable resistor 32 constitute a temperature detection bridge. The temperature detection side terminal voltage on the thermistor 29 side is connected to the non-inverting input terminal of the comparator 33, and the temperature setting side terminal voltage on the variable resistor 32 side is connected to the inverting input terminal. Comparator 33
The output terminal 34 of energizes the room temperature detection relay R _H via the NPN transistor 35 and
Connected to the input terminal of G ₂ . The diode 36 disables the temperature detection side so that room temperature detection starts after the timer circuit of the drying control means B operates.

Next, the operation will be explained based on the operation sequence diagram shown in FIG. After washing the private parts of the human body with washing water, turn on the drying switch 17 at time to, R-
The "" output of the S flip-flop 19 switches from "H" to "L", and the resistor 21 is connected to the capacitor 22.
Charging begins via Then, both of the two input voltages of the gate _G1 become "L", and the output becomes "H" by the NOR logic. The output of gate _G2 becomes "H" due to OR logic, and the drying relay R _F
energize. Therefore, the contact point R _Fa is closed, and the commercial power source 15 is supplied to the blower fan motor 10 and the drying heater 11, and the drying of the buttocks begins. When the terminal voltage V _c of the capacitor 22 reaches the timer time setting voltage V _T ,
The output of comparator 25 is inverted to "H". At this time, the diode 36 becomes reverse biased and a temperature detection operation becomes possible, but if the room temperature has not reached the detection value voltage, the output of the comparator 33 remains unchanged and is fixed at "L". This is a so-called low room temperature state. Therefore, the room temperature detection relay R _H remains off, the output of the gate _G1 is inverted to "L" by the NOR logic, and the drying relay R _F is turned off. and NPN transistor 2
The collector terminal voltage of 8 is input to the reset terminal of the R-S flip-flop via the reset circuit 29, and hot air drying is stopped at time _t1 .

From time t ₂ to t ₄ , the room temperature of the toilet is relatively high, and from time t ₂ to t ₃ , as described above, at t ₃ , the comparator 33
The voltage at the output terminal 34 of is inverted to "H". Therefore, the room temperature detection relay R _H is energized, the contact R _Hb is opened, and the energization of the heater 11 is stopped. Meanwhile dry relay
_RF does not turn off because the output voltage of the comparator 33 is input to the gate _G2 , and enters the so-called ventilation mode. At time _t4 , the drying stop switch 18 is turned on and everything returns to its initial state.

In the above configuration, by turning on the drying operation switch, hot air drying operation is performed for a predetermined time,
If the room temperature in the toilet is high, it can automatically switch to ventilation mode. Another advantage is that the room temperature detection level can be set arbitrarily, and the drying stop switch allows you to set the drying time to your preference.

The same effect can be obtained by linking the seat switch built into the toilet seat and automatically stopping the air blowing when the toilet seat is stood up.

Effects of the Invention As described above, according to the sanitary washing and drying apparatus of the present invention, the following effects can be obtained.

The toilet includes a room temperature detection means for detecting the room temperature of the toilet, and a drying control means for energizing the hot air drying means for a predetermined period of time and switching the air drying means to the ventilation mode based on the room temperature detection setting value of the room temperature detection means. In the summer, when the room temperature in the toilet is high, the buttocks become sweaty due to hot air drying, and the discomfort of wearing hot clothes can be avoided.
